Following up on the recently released mobile game and the announcement of an upcoming card game, Netflix is continuing to mount an all-out marketing blitz for the second season of Stranger Things with a brand new trailer. The trailer pretty much confirms the return of a key character (which shouldn’t come as a surprise) and the addition of some new cast members including Paul Reiser and Sean Astin (more ’80s pandering FTW!). There’s also a glimpse of an even bigger monster and just generally a lot of crazy shit happening in Hawkins, Indiana. All nine episodes of Stranger Things: Season 2 arrive on Netflix on Oct. 27th; check out the trailer after the jump and see what you think.
